NEW YORK ATI Allegheny Ludlum Corp. has halted production from one of the furnaces at its Latrobe, Pa., facility following an explosion July 24.
No one was injured in the blast, while the airmelt furnace involved is being tested and is expected to be back online "in a matter of days," an ATI spokesman told AMM.
While an investigation is ongoing, the spokesman said it appears the explosion was caused by moisture entering the furnace as it was being charged.
The incident did not cause any damage to the furnace itself, but did blow sheet metal off the facilitys roof and wall, he added. The facility was promptly evacuated.
The Latrobe facilitys vacuum-arc remelt (VAR) furnaces were not affected by the incident and continue to operate. Shipments are unlikely to be affected by the production halt, the spokesman said. "Whatever heats they lost, theyll be able to catch up," he added.
The Latrobe facility produces many of Allegheny Ludlums and ATI Allvacs specialty steel and nickel-based alloys, according to the companys website.
